Moths & Butterflies

A Pathfinder HonorSlide2

1.

Define the following

terms

.Slide3

Antennae

- paired

appendages connected to the front-most segments of an insect. Antennae are jointed, at least at the base, and generally extend forward from the head. They are sensory

organs - sensing touch, air motion, heat, vibration (sound), and especially smell or taste.Slide4

Cocoon-

cocoon is a casing spun of silk

as

a protective covering for the pupa.Slide5

P

upa - A

pupa is the life stage of some insects undergoing transformation

.Slide6

Larva - a

juvenile form

an insect that is undergoing metamorphosis. The

larva can look completely different from the adult form, for example, a caterpillar differs from a butterfly. Larvae often have special (larval) organs which do not occur in the adult form.Slide7

Chrysalis - A

chrysalis or

nympha

is the pupal stage of butterflies. Chrysalids are often showy and are formed in the open. Most are

attached to a surface by a Velcro-like arrangement of a silken pad spun by the caterpillar and a set of hooks at the tip of the

pupal

abdomen.Slide8

2.

What is the distinction between moths and butterflies?Slide9

Antennae / Feelers

Moths

have

comb-like or feathery antennae, or filamentous and

unclubbed

.

Butterflies

thin

slender filamentous antennae which are club shaped at the end. Slide10

Pupae

Moths

spin

a cocoon made of silk within which they metamorphose into the

pupal

stage.

Butterflies

form

an exposed pupa which is also termed as a chrysalis.Slide11

Coloration

of Wings

Moths

Nocturnal

moths

are

usually plain brown, grey, white or black and often with obscuring patterns of zigzags or swirls which help camouflage them as they rest during the day.

Many day-flying

moths are brightly-colored, particularly if they are toxic.

Butterflies

have

bright

colors

on their

wings.

A few butterflies are also plain-colored, like the Cabbage White butterfly.Slide12

Time of Activity

Moths

are nocturnal – night activity

There are however exceptions, including the diurnal Gypsy moth and the spectacular "

Uraniidae

" or Sunset moths

Butterflies

are

diurnal – both day and night activitySlide13

Resting Posture

Moths

usually

rest with their wings spread out to their sides.

Butterflies

frequently

fold their wings above their backs when they are perched although they will occasionally "bask" with their wings spread for short periods.Slide14

4. What causes colored powder to come off on your hands when you handle the wings of a butterfly or moth? Slide21

This powder is made from tiny scales which cover the butterfly's wings. These scales give the wings their color, as the membrane beneath the scales is nearly transparent. The scales detach when

contacted

by a finger, much as the skin on a person's knee is abraded when it contacts a sidewalk.Slide22

. Name

some

harmful tree moths and harmful house moths. Tell during what stage of their lives they each do their damage.Slide24

Gypsy Moth

The gypsy moth was introduced into the United States in 1868 by a French

scientist. It

is now one of the most notorious pests of hardwood trees in the Eastern United States.

Gypsy moths eat only during their larval stage.Slide25

Tent Caterpillar

Species

occur in North America, Mexico, and Eurasia. Twenty-six species have been described, six of which occur in North America.

Caterpillars build

a single large tent which is typically occupied through the whole of the larval stage. Slide26

Lesser Wax Moth

Wax moths were first seen in North America in 1806. People believe they came over with honeybees from Europe

..

The larvae are the only ones that eat, the adults will not eat.Slide27

Codling Moth

Coddling moths are known as an agricultural pest, their larva being the common apple worm or maggot. It is native to Europe and was introduced to North America, where it has become one of the regular pests of apple orchards. Slide28

Clothing Moth

Like

most moth caterpillars, it can (and will) derive nourishment not only from clothing but also from many other

sources. Eggs hatch into larvae, which then begin to feed. Once they get their fill, they pupate and undergo metamorphosis to emerge as adults. Slide29

White Shouldered Moth

The White Shouldered House Moth

is

a very common moth and occurs regularly inside buildings, and being continuously-brooded, can be found at any time of year, mainly found indoors via open doors, windows etc. It is a widely distributed species whose larvae infest stored grainSlide30

. What famous butterfly follows the birds southward every winter and comes northward in the spring ?Slide31

Monarch Butterfly

Monarch butterflies are especially noted for their lengthy annual migration. They make massive southward migrations starting in August until the first frost. A northward migration takes place in the spring. Female Monarchs deposit eggs for the next generation during these migrations. By the end of October, they reach their overwintering grounds.

How

the species manages to return to the same overwintering spots over a gap of several generations is still a subject of research; the flight patterns appear to be inherited, based on a combination of circadian rhythm and the position of the sun in the sky.Slide32

7.

Describe the life cycle of a butterfly or moth.

What

lesson can be learned in connection with the resurrection of the righteous.Slide34

Butterflies and moths are notable for their unusual life cycle with a larval caterpillar stage, an inactive

pupal

stage, and a spectacular metamorphosis into a familiar and colorful winged adult form

.

Unlike many insects, butterflies do not experience a nymph period, but instead go through a

pupal

stage which lies between the larva and the adult stage.

The four stages of a butterfly's life cycle are…..Slide35

Butterfly

eggs are fixed to a leaf with a special glue which hardens rapidly. As it hardens it contracts, deforming the shape of the egg.

Eggs

are usually laid on plants. Each species of butterfly has its own host plant range and while some species of butterfly are restricted to just one species of plant, others use a range of plant species, often including members of a common family.

Stage 1 - EggSlide36

Larvae

, or caterpillars, are multi-legged eating machines. They consume plant leaves and spend practically all of their time in search of food. Caterpillars mature through a series of stages, called instars. At the end of each

instar

, the larva moults the old cuticle, and the new cuticle rapidly hardens and pigments. Development of butterfly wing patterns begins by the last larval instar

.

Stage 2 - CaterpillarSlide37

When the larva is fully grown, hormones are produced. At this point the larva stops feeding and begins "wandering" in the quest of a suitable pupation site, often the underside of a leaf. The larva transforms into a pupa (or chrysalis) by anchoring itself to a substrate and molting for the last time. The chrysalis is usually incapable of movement, although some species can rapidly move the abdominal segments or produce sounds to scare potential predators.

Stage 3 - PupaSlide38

the

adult, sexually mature, stage of the insect is known as the imago. After it emerges from its

pupal

stage, a butterfly cannot fly until the wings are unfolded. A newly-emerged butterfly needs to spend some time inflating its wings with blood and letting them dry, during which time it is extremely vulnerable to predators. Some butterflies' wings may take up to three hours to dry while others take about one hour.

Stage 4 - ImagoSlide39

Resurrection

The life cycle of the butterfly has parallels to the life cycle of a Christian. During the larval stage, a butterfly lacks the beauty of an adult. It spends all of its time feeding itself, often causing major damage to plants. This stage of a butterfly's life can be likened to the

unrighteous state

of man, in that it is unlovely and often ignorant of the damage it causes.

Eventually, the caterpillar pupates. This stage is parallel

to death.

While inside its chrysalis, the butterfly is transformed. This is not something it is conscious of doing. At the resurrection of the righteous, the Christian will also transformed by Christ into a new person, free from all defects. Gone are the selfish desires and the ugliness. It is a beautiful creature free from sin.Slide40

antiopa, Linnaeus 1758) The mourning cloak (also known as

Camberwell

beauty) is a butterfly with unusual forewing outlines. The dark maroon wings have pale, speckled edges and a dark inner margin with blue spots. Eggs are laid in large clusters on elm, poplar, and willow trees. The caterpillar is black with white spots and has maroon patches on the back. This larva eats the leaves of poplar, elm,

salix

, and

betula

. Adults sip fermenting fruit juices, oak sap, and flower nectar. The mourning cloak is found in

riparian forests

in Europe, North America, and temperate areas in Asia.Slide59

Passiflora

); the adult sips nectar from the flowers of the lantana and shepherd's needle.

Julias

are found from South and Central America to the southern USA. The Julia belongs to the

Heliconians

, tropical butterflies that have a large head and have a bad taste and smell. It is a brush-footed butterfly (Family

Nymphalidae

).Slide60

Karner Blue Butterfly

The

Karner

Blue Butterfly (Lycaeides

melissa

samuelis

) is a small, blue butterfly that has a wingspan of about 1 inch (2.5 cm). This endangered species lives in oak savannas and pine barrens and is associated with wild lupine (

Lupinus

perennis

, a plant that the caterpillar eats). Adults drink the nectar of horsemint,

butterflyweed

, and bachelors button. The adult male (pictured above) and female have a very different appearance. The upper sides of the male's wings are silver to dark blue with white and black margins. The upper sides of the female's wings are gray-brown to blue, with some bands of orange crescents along the bottom of the hind wing, and white and black margins. The underside of the wings of both sexes are grayish in

colorwith

orange crescents and some metallic spots along the bottom of both hind wings. The green caterpillar is tended by ants; these ants collect a sugary liquid that is secreted by the caterpillar, and the ants protect the caterpillar from some predators and parasites.Slide61

Monarch Butterfly

The Monarch (

Danaus

plexippus) is a common poisonous butterfly found worldwide. It eats milkweed in its larval stage and lays eggs on the poisonous milkweed plant. Monarchs have a wingspan of 3 3/8 - 4 7/8 inches (8.6 - 12.4 cm).Slide62
